To all whom '25 may concern.'

Be it known that we,GE1 iARD JorrN PHIL- Lirs andLoUrs lAiv'rrro'ivrKELLER, subjects of the King 'of Great Britain 'and Ireland, residing,respectively, London, lEngland, have invented Improvements Relating toStowing and v'lrafn'sfereifce rf Boats on Board Ship, of which thefollowing is "a specification. l y

This invention has reference to apparatus for enabling boats "to, besecurely stowed side by side in 'rows athwartship andtobe transferredsuccessively to `arran'g'enents for lowering them over the side of theship.` In such apparatus it has been proposed to provide a transverselyarranged tilting frame provided lwith rails to suspend the `boats fromtrolleys runnin-g `-onY an ,overhead rail that forms part of a cagewhich thebo'ats are held and which is 'capable of being caused ytotravel along the rails of the tilting frame so that the cage will'extend over the ships side sufliciently to enable the boats to belowered into the water by means of tackle attached to the ends of thecage.

Now, in means according to the present invention, the rails of aVtransversely arrangedytilting iframe support rollers mounted at thestein and stern of each boat and the boats, when stowed, are held at thedesired distance apart by stops easilyoperable to release the boats andperinit them to move under the action of gravity toward' an independentdavit arrangement by ,which they are received from the iframes andlowered over the si e `of the ship. lIn combination with Ithe tiltingframe wl'iich, supports the boat trolleys there are provided side framesor checks adapted to normally hold the boats securely to the fram@ butadapted to be displaced so as to release the boats, for instance bymeans lof a' Heat or floats actuating the boat-holding side 4frames orchocks inthe event of the ship oundering. The boat holding side framesor checks and the ,davit arrangements are A preferably of the kinddescribed in the specification of our former Letters Patent No.,1,210,580 dated 2 January i917. The side fraines or chocks on thetilting trame are or may be arranged so as to be released by hand Aorother ine'ans, the actuating shafts ofthe boat 4chocks being linked orotherwise connected and acting either separately or `as a whole.

The keel of each boat ,is or may be sup- Poted by a bar .or frame ,more0r less conf.

forming to the stem, keel and stern of the boat and having forwardly andrearwardly projecting trunnions which rest `upon Isuitable supportsbelow the level of the boat roller rail'; t e supports are slightlyrecessed in the middle to receive the trunnions and depressions ornotches are formed alongside the trunnion supports, the arrangementbeings'uci 1that 4the boats being released from theiiy-holding sideframes or chocks and from the stops l`which engage the boat rollers,e'a"h boat will inoye along tlieiails, carrying its keel-supporting baror frame with it until the trunnions of thelatter drop 'into theldepressions or notches when the bar oryfiame vwill be left behind.

The tilting frame, which conveniently comprises side girder-like membersformed at the top 4as rails a and connected together at the bottoin; theframe is mounted on pivots Z) "at the center o'f its length and can betilted so as to incline downwardly toward either side of the shi`p';,thetilting of the frame inlay be veiie'ctefd in any `convenient manner, forinstance by means ci' a screw `c connected to the tilting frame by alink (Z and worked up or down by a worniedriven nut Ae prevented fromnioving longitudinally oixthe screw.s l

Each bolt f has a 'roller g mounted at its stein and stern the rollersrunning on the rails a and being held by stops which niay be inthe formof pairs `of pinsr Zi attached to weig ited levers 'i and projectingupwardly through holes vin the rails o as shown. Lifting ofthe weightedlevers withdraws the pins Zt and releases the boat.

yOn the inner side of each rail ci is fixed a barkl formedy withdepressions or notches Z as sho-wn in Fig. 3 at each boat position thebar `hetiveen eachA pair of depressions or notches Z being slightlyrecessed at m; in the recesses at m rest roller-like trunnions n of abai o which lserves to support the keel of the stowed boat throughoutits length. Instead of the rollers of the keel supporting bar resting inrecesses in the bar le, this bar may be made with a flat between thedepressions Z and a pair of pins working in con-y Fig. l is alSOjunction with the pins h bearranged to hold the keel supporting bar inposition until the boat is released. This arrangement is shown in Fig.t, h1 being the additional pins which are attached to the plate carryingthe pins h.

p, p are side frames or checks of the kind described inthe specificationlof our former Letters Patent No. 1,210,530 dated 2 J anuary, 1917 theseside frames or chocksV are pivoted to longitudinal members of thetilting frame and each set is provided with an actuating shaft Q andreleasing bell cranks 9 as described in said specification. To the endof each shaft g is fixed an arm s by which the shaft can be turned andeach arm s is connected through a pin and slot connection t with asliding rod u; this rod is coupled to a bell crank lever v one arm v1 ofwhich is curved and extends over an upwardly extending rod tw 1providedwith a float m which, in the event of the vessel foundering, will movethe rod w into contact with the arm v1 and shift the sliding rod u tothe left and, through the arms s, shafts g and cranks 1, release theside frames or checks p of all the boats. The curve of the arm @l isstruck from the center of the pivots of the tilting frame so thatassuming the parts are in the normal position shown, tilting of theframe will not prevent the float from properly actuating the side frameor chock releasing mechanism.

The weighted levers to which the stop pins are attached by links asshown can be held in the positions corresponding to the raised andlowered positions of the stop pins by pins y that can be inserted inholes in the framing below the levers i to prevent the levers beinglowered, or inserted in the same holes above the said levers when suchlevers are lowered, to prevent the levers being raised. The levers 'iare fixed on shafts extending froml side to side of the tilting frameeach shaft having a lever at each end the stop pins at the bow of a boatbeing attached to the one lever and those at the stern to the other.

As each boat arrives at the end of the rails, it is held by stop pins7b2 until the davit tackle has been fixed, when the stop pins .7b2 arelowered and the boat swung over` board on the davit tackle; the pins h2are required to prevent the boats prematurely leaving the tilting frameand their levers z' are not provided with pins y.

The end portions of the rails may extend beyond the main portion of thetilting frame and be inclined downwardly toward th'e sides of the ship.-

Assuming it is desired to launch the boats, the tilting frame isinclined downwardly toward the desired side of the ship, say to- Copiesof this patent may be obtained for ward the left side,y by actuating'thewormdriven nut e in the required direction.Y The boat nearest the leftisthen released from its chocks p by actuating the lever s.

Y The lever z' connected to the pins h which -hold this boat is thenactuated so as to lower these pins; the boat then travels on itsVrollers g downI the rails a of the inclined frame, the bar '0" movingwith it until the bar trunnions a enter thelower notches fm, when thebar will1 be held. The boat is held by the stop pins at the lower end ofthe tilted frame until swung out` on the davit tackle. *Each succeedingboat is released in the same way.

If the ship founders, the chocks of all the boats will be released assoon as the water lifts the floatwhich ythen actuates the lever w andthen shifts the rod u and all the levers s of the chock releasing gear,leaving the boats free to float when the water reaches them. l p

What We claim iss-f` 1. Means for stowing boats 'on board shipcomprising a frame `adapted to be tilted toward either side of the 'shipand formed orv provided with rails, wherein the rails serve as a trackfor rollers mounted at the bow and vstern of leach boat, and stops areprovided to hold the boats in their stowed positions on the' supportingrails and adapt-` ed when released, to allow the boats to move along therails toward independent davit arrangements by which theycan. be loweredover the side of the ship, substantially as described.,

2; In means 4for A ship according to claim 1, side frames or chocksadapted toysecure the boats to the tilting frame and to be displaced soSas` to stowing `boats' on, board l release the boats by actuating meansthe side frames'or checks of the boats `being operable separately or asawhole, substan-4 tially as described.

3. In means for stowing boats on board ship according to claim 1 thecombination with the track rails for the boat rollers, of`

supports at a lower level upon which rest the trunnions of bars orframes each adapted to normally support the keel of the boat, the saidtrunnion supports being so shaped that as a boat moves along the rails,the keel supporting bar or frame will clear the keel of the boat and beleft behind, substantially as described. p A.
